ok, I cant login

I don't know the script either, but one thing to be aware of if the password is stored in a database: many scripts don't store the literal password, they store a hash of the password.

In years past I've seen MD5 used quite often for passwords, I don't know what's hot now.

You can get an MD5 hash of a desired password with PHP like so:

<?php echo md5('your_password'); ?>

(Note: I haven't tested the above code.)
